With the propagation of ultrasonic vibration in the medium, its essence is the mechanical vibration is propagating in the elastic medium in the form of wave, it is generally considered that its frequency should be above 20 kHz. Ultrasonic non-destructive testing commonly used at 0 4 to 5 MHz. Ultras

1. Piezoelectric ceramic transducer, if they differ in diameter, then, is there a difference in frequency? And, under the same size, why is the vibration large or small?As for piezoelectric ceramic crystal, if they differ in diameter, then it will definitely affect its frequency. However, if the dia

1. Piezoelectric ceramics, how can it be applied? And why do piezoelectric ceramics have to use ferroelectric materials?For piezoelectric ceramics, to make it useful, there must be a piezoelectric effect. Otherwise, it is no different from ordinary ceramics. As for piezoelectric ceramics, ferroelect

There is a simple way to collect the amount of electricity generated by piezoelectric discs transducer. Specifically speaking, the piezoelectric ceramics are connected in series or in parallel according to the voltage level, and the required direction force should be the same. Then, through the high

1. What are the specific applications of piezoelectric ceramics?(1) The piezoelectric discs transducer is sensitive to this characteristic, and it can convert mechanical vibration into an electrical signal. Therefore, it can be used well in such fields as sonar systems, weather detection, and teleme
